Britain's navy and air force have spent at least ten days searching for what the country's media have called a "Russian submarine", the BBC reported.
The country's defense ministry did not confirm that it was looking for a foreign submarine in its statement. This is the third time the UK has conducted search operations, according to the Telegraph, with the previous instance tied to demands for higher defense spending.
"We can confirm that allied maritime patrol aircraft based at RAF Lossiemouth for a limited period are conducting activity with the Royal Navy. We do not discuss the detail of maritime operation," the spokesman of the UK's defense ministry said.
Media paranoia about "Russian submarines" is prominent in Northern Europe, particularly in Sweden, where the phenomenon goes back decades. The Swedish military recently revealed that most of the violations of its borders were made by the United States, while much-feared Russia shared second place with Germany.
